Actually this problem is "under warranty". As previously posted they ARE offering to replace it for "free" if I pay $20. I am by no means an English professor but if I have to pay $20 it is not free, it costs $20. They own it and want to replace it with more of the equipment they own as it is defective. The principle here is $20 is not FREE and the only way to avoid that free fee is to pay $70 a year. Pretty simple... if its a free replacement of their faulty equipment I shouldn't have to pay or get extorted to take a $70 a year plan to correct this issue.
This has probably already been covered, but here goes:
You should have known about these possible charges when you signed up. If you didn't, that's your fault. If you haven't called back, try calling again, another csr may waive the shipping fee. BTW, they aren't charging to replace it, they are charging to ship it, there is a difference. Good luck!
